LSU AgCenter's Plant Diagnostic Center chief Raj Singh says citrus canker was found last month in St. Bernard Parish. It was found last year in Plaquemines Parish - Louisiana's citrus center - and in New Orleans and Jefferson and St. Charles parishes.

He said greening has been found in New Orleans and in Washington Parish.

Plaquemines Parish grower Ben Becnel Jr. said that with 5,000 trees, there's no way to check each one regularly. He says he keeps an eye out while working in the orchards.
